Ribose

Nucleic acids may contain deoxyribose sugars, as is the case for DNA, or ribose sugars, which are found in RNA. Ribose differs from 2’-deoxyribose in that a hydroxyl group is bonded to its 2’ carbon rather than a hydrogen atom, as shown here.

Question 1: ____________ sugars are mainly in RNA but not DNA.
  1. Ribose
  2. Deoxyribose
  3. Monosacchride
  4. Disaccharide


Answer 1 Answer - (a) Ribose

Question 2: How does the ribose structure differ from the 2’-deoxyribose?
  1. Ribose has an RNA component, while 2’-deoxyribose is made of DNA.
  2. Ribose differs from 2’-deoxyribose in that a hydroxyl group is bonded to its 2’ carbon rather than a hydrogen atom.
  3. Ribose differs from 2’-deoxyribose in that a hydroxyl group is bonded to its 5’ carbon rather than a hydrogen atom.
  4. Ribose differs from 2’-deoxyribose in that a hydrogen atom is bonded to its 2’ carbon rather than a hydroxyl group.


Answer 2 Answer - (b) Ribose differs from 2’-deoxyribose in that a hydroxyl group is bonded to its 2’ carbon rather than a hydrogen atom.
